This book is both a tribute to Professor Rao and a state-of-the-art information concerning certain aspects of hydrologic past, present, and future. Specialists and experts from all parts of the world, including both developed and developing countries contributed to this publication. This book will be of interest to researchers and consultants.

HYDROLOGY AND HYDRAULICS <> The subject matter in this book is divided into four sections.

Section I is comprised of four chapters. Beginning with a short biography of Professor Rao in the first chapter, history of hydraulic engineering at Purdue University is given in chapter 2. Soft computing approaches are discussed in chapter 3 and training of artificial neural networks is presented in chapter 4.

Section IV is on hydraulics and comprises five chapters. Stage discharge and sediment rating curves are discussed in chapter 25, streamflow measurements and discharge assessment during high flows in chapter 26, mathematical modeling of flow routing in open channels in chapter 27, soil erosion and sediment yield modeling in chapter 28, hydraulic modeling of watershed erosion in chapter 29, and hydrodynamic transport in flow with vegetation subject to waves and currents in chapter 30.
